    The main content of this report is the identification and definition of market mechanisms for Application Layer Networks (ALNs). On basis of the structured Market Engineering process, the work comprises the identification of requirements which adequate market mechanisms for ALNs have to fulfill. Subsequently, two mechanisms for each, the centralized and the decentralized case are described in this document. These build the theoretical foundation for the work within the following two years of the CATNETS project. --Grid Computing

    In this paper the requirements for an ALN simulation environment are analysed, as needed in the CATNETS Project. A number of grid and general purpose simulators are evaluated regarding the identified requirements for simulating economical resource allocation mechanisms in ALNs. Subsequently a suitable simulator is chosen for usage in the CATNETS project. --CATNETS simulator,requirements analysis,simulator selection

    Is there an intra household Kuznets curve? Some evidence from the Philippines

    Get PDF
    Is there a"Kuznets curve"for intra household inequality ? Does intra household inequality first increase, peak, and then decrease as the household becomes better off? The authors found both theoretical and tentative empirical support for this hypothesis. The policy significance of this finding is that the benefits of an increase in household well-being need not fully trickle down to the most disadvantaged members of the household. This is particularly true for the poorest households. This finding should be taken into account in the design of supplementary feeding programs.Poverty Lines,Environmental Economics&Policies,Inequality,Housing&Human Habitats,Poverty Assessment

    In this work the self-organising potential of the CATNETS allocation mechanism is described to provide a more comprehensive view on the research done in this project. The formal description of either the centralised and decentralised approach is presented. Furthermore the agents' bidding model is described and a comprehensive overview on how the catallactic mechanism is incorporated into the middleware and simulator environments is given. --Decentralized Market Mechanisms,Centralized Market Mechanisms,Catallaxy,Market Engineering,Simulator Integration,Prototype Integration

    Supply response of West African agricultural households

    This paper explores the implications of preference heterogeneity between wives and husbands in nonresource-pooling rural West African households for the effect of crop price changes on agricultural production, i.e., their supply response. A "semi-cooperative" game-theoretic model of household decisionmaking, in which household members make unilateral time and income allocation decisions and negotiate over who controls these resources, is proposed. The model is used to show that Pareto efficiency in both production and consumption do not hold. It is then employed to simulate the supply response to cotton price increases accompanying agricultural sector liberalization in Burkina Faso in the early 1980s. The simulated semi-cooperative model predicts the cotton supply response of (monogamous) Burkinabé households to be 25 percent below that which would ensue in households facing the same production constraints yet whose members have identical preferences. The analysis indicates that in nonresource-pooling agricultural households, preference heterogeneity can be expected to mute supply response and may do so in a quantitatively significant manner. It illustrates how an intrahousehold approach that allows for such heterogeneity and for disaggregation of resource control by gender contributes to a better understanding of price effects.Gender ,Resource management. ,Households Decision making. ,Household resource allocation ,

    Rational bidding using reinforcement learning: an application in automated resource allocation

    Get PDF
    The application of autonomous agents by the provisioning and usage of computational resources is an attractive research field. Various methods and technologies in the area of artificial intelligence, statistics and economics are playing together to achieve i) autonomic resource provisioning and usage of computational resources, to invent ii) competitive bidding strategies for widely used market mechanisms and to iii) incentivize consumers and providers to use such market-based systems. The contributions of the paper are threefold. First, we present a framework for supporting consumers and providers in technical and economic preference elicitation and the generation of bids. Secondly, we introduce a consumer-side reinforcement learning bidding strategy which enables rational behavior by the generation and selection of bids. Thirdly, we evaluate and compare this bidding strategy against a truth-telling bidding strategy for two kinds of market mechanisms – one centralized and one decentralized

    Performance Evaluation - Annual Report Year 3

    This report describes the work done and results obtained in third year of the CATNETS project. Experiments carried out with the different configurations of the prototype are reported and simulation results are evaluated with the CATNETS metrics framework. The applicability of the Catallactic approach as market model for service and resource allocation in application layer networks is assessed based on the results and experience gained both from the prototype development and simulations. --Grid Computing

    In this paper the simulation environment for the CATNETS project is defined further. The chosen simulator is adopted in terms of new features an architecture changes in order to provide a valid simulation environment for Application Layer Network scenarios. Furthermore the requirements for a scenario generator and the needed configuration mechanisms for the actual simulation runs are introduced. --Grid Computing
